Returns : | A GDBus timeout in milliseconds. -1 when default timeout for GDBus should be used.

### ibus_get_user_name ()

    const gchar *       ibus_get_user_name                  (void);

1. `getlogin()`

2. Environment variable SUDO_USER

3. Environment variable USERHELPER_UID

4. Environment variable USERNAME

5. Environment variable LOGNAME

6. Environment variable USER

7. Environment variable LNAME

Returns : | A newly allocated string that stores current user name.

### ibus_init ()

    void                ibus_init                           (void);

Init the ibus types.

It is actually a wrapper of `g_type_init()`.

### ibus_key_event_from_string ()

    gboolean            ibus_key_event_from_string          (const gchar *string,
                                                             guint *keyval,

Parse key event string and return key symbol and modifiers.

`string` : | Key event string.
`keyval` : | Variable that hold key symbol result.
`modifiers` : | Variable that hold modifiers result.
Returns : | TRUE for succeed; FALSE if failed.

### ibus_key_event_to_string ()

    const gchar *       ibus_key_event_to_string            (guint keyval,
                                                             guint modifiers);

Return the name of a key symbol and modifiers.

For example, if press ctrl, shift, and enter, then this function returns: Shift+Control+enter.

`keyval` : | Key symbol.
`modifiers` : | Modifiers such as Ctrl or Shift.
Returns : | The name of a key symbol and modifier.

### ibus_main ()

    void                ibus_main                           (void);

Runs an IBus main loop until `ibus_quit()` is called in the loop.

See also: `ibus_quit()`.

### ibus_quit ()

    void                ibus_quit                           (void);

Stops an IBus from running.

Any calls to `ibus_quit()` for the loop will return. See also: `ibus_main()`.

### ibus_set_display ()

    void                ibus_set_display                    (const gchar *display);

Set the display address.

`display` : | Display address, as in DISPLAY environment for X.

### ibus_set_log_handler ()

    void                ibus_set_log_handler                (gboolean verbose);

Sets GLIB's log handler to ours. Our log handler adds time info including hour, minute, second, and microsecond, like:

(ibus-daemon:7088): IBUS-DEBUG: 18:06:45.822819: ibus-daemon started

If `verbose` is `TRUE`, all levels of messages will be logged. Otherwise, DEBUG and WARNING messages will be ignored. The function is used in ibus-daemon, but can be useful for IBus client programs as well for debugging. It's totally fine for not calling this function. If you don't set a custom GLIB log handler, the default GLIB log handler will be used.

`verbose` : | TRUE for verbose logging.

### ibus_unset_log_handler ()

    void                ibus_unset_log_handler              (void);

Remove the log handler which is set by ibus_set_log_handler.

### ibus_write_address ()

    void                ibus_write_address                  (const gchar *address);

Write D-Bus address to socket file.

See also: `ibus_get_address()`.

`address` : | D-Bus address of IBus.
